Scaphoidkus consors Uhler. (Plate X, Fig. 4). 

 Scaphoideus consors Uhler. Trans. Md. Acad. Sci., I, p. 36 (1889), Van 

 Duzee, Catalogue Jassoidea, Trans. Am. Ent. Soc, Vol. XXI, p. 300- 



Ochreous brown, marked with white and fuscous. Vertex 

 wider than long, angulate. Length to tip of elytra 

 5.25-5.75 mm. 



Head rather obtusely angulate in front ; vertex, length 

 five-sixths of width, front with sides nearly parallel, narrow- 

 ing sharply to apex; clypeus widening at tip; lorae broad, 

 outer border semi-circular, reaching to or merging with border 

 of cheek. Nodal vein of elytra arising from outer anteapi- 

 cal cell. 



Color: "Dull, pale, clay brown inscribed with white and 

 fuscous." 



Genitalia: 9 , last ventral segment long, hind margin 

 sinuate, scarcely notched at center, lateral angles rounded; 

 pygofers moderately robust, with light brown bristles scat- 

 tered over the surface, and more numerous near tip. 



Specimens referred to this species are in hand from New 

 York (Southwick), Washington, D. C. (Mally), and from 

 National Museum, "Relay Station, Md.," and "Texas (Bel- 

 frage)," 



While it is difficult to locate very positive characters, 

 there seems to be, as stated by Van Duzee, sufficient reason 

 to separate it from scalaris. However, my material of typical 

 consors, or of specimens that would show its affinities with 

 other forms, is too scanty to permit of definite conclusions. 



Var. unicolor. n. var. (Plate X, Fig. 5, 5a), similar in size 

 and shape to consors, but of a dense brown color with mark- 

 ings nearly or entirely obliterated. Face uniform brown, 

 pectus and venter dark brown or fuscous. Ocelli red. Elytra 

 dark brown, nodal vein broadly and densely marked with 

 fuscous. The last ventral segment of female is shorter, more 

 truncate, and the pygofers short, more robust, and bristles 

 confined more to margin and tip. The cT valve is large, rather 

 narrow, plates elongate triangular, outer margin slightly 

 convex, the flaccid tips rufous and reaching to beyond tip of 

 pygofers. 



One specimen, Berkeley Springs, W. Va., and three, Deca- 

 tur, Ala., received from Mr. E. D. Ball.
